CHOROID PLEXUS
The choroid plexus is a structure present inside the brain ventricles. It has two main components: an epithelium and blood capillaries
The epithelium is formed by a single layer of specialized, cuboidal epithelial cells (choroid epitheliocytes) that cover a rich network of fenestrated capillaries. The choroid epitheliocytes produce and secrete the blood-cerebrospinal fluid (CSF) into the cavities of the brain.
The epithelium and its underlying tissue are folded into numerous villi, and this arrangement increases the volume of the choroid plexus for CSF production.

The image is of a small region of the choroid plexus located on the surface of the cerebellum, which is the organ located to the left of the choroid plexus.
The epithelium lining the choroid plexus was shown in the Epithelial Tissue Module as an example of simple cuboidal epithelium. Click to review the epithelium.
